Ladder (Merriam-Webster Dictionary)

1 : a structure for climbing up or down that consists essentially of two long sidepieces joined at intervals by crosspieces on which one may step.

2 : something that resembles or suggests a ladder in form or use; especially : RUN

3 : a series of usually ascending steps or stages : SCALE

In Ladder Leagues, each Player's objective is to climb the Ladder and reach the Top, i.e. #1. Each step on the Ladder is called Rank; the Highest Rank is #1 followed by #2 then #3 and so on.

• The Ladder Ranking is based on Matches Played Results.
  
  
• When a New League starts, Players will be Ranked in order of Joining sequence; the first Player will be #1, the next Player will be #2, and so on.
  
  
• When you first join you are placed at the bottom of the Ladder.
  
  

• The Ranking is updated on the spot after each Match is reported.
  

• When you defeat a higher ranked Player you move up Half the Distance between their rank and your own. Example:

If your Rank is 3274 and you defeat the Player Ranked 1258, your rank becomes (3274+1258)/2 = 2266.

If your Rank is 165 and you defeat the Player Ranked 12, your rank becomes (165+12)/2 = 138.

• Your rank on the Ladder does not change or go down if you lose a match unless your opponent is ranked Directly below you. Example:

If your Rank is 32 and you are defeated by the Player Ranked 33, your rank becomes 33 and your opponent Rank becomes 32.

• When a Player moves to a Rank above you, your Rank will go down.
